This article shows how to use Xcode scheme pre-/post-actions (Build and Run) to observe how your app creates and mutates defaults, by logging changes outside the app process. What are Defaults? In Swift and macOS development, defaults (via UserDefaults and the defaults CLI) are the lightweight persistence layer for user preferences, feature toggles, and other small pieces of state that need to survive app relaunches. They sit between in-memory settings and heavier storage options, letting you read and write simple values keyed by domain so the same code works in app code, Xcode schemes, and shell scripts. Because defaults are global to a domain, careful naming and clean-up are essential to avoid collisions and stale settings during development. ...

Integrating Python-based machine learning models into iOS applications can be challenging, particularly when converting models into a Swift-compatible format. This example will demonstrate a simple image classification task using the Fashion-MNIST dataset and CoreML conversion tools. The goal is to illustrate the effort required to deploy small-to-medium complexity ML models within iOS applications. The demonstration is based on a Convolutional Neural Network (CNN) built with PyTorch, but the concepts apply broadly to other Python-based models as well. ...

Why Swift? Data science is dominated by Python and R, with some usage of Julia, Scala, Java, and C++. While Swift may not be the most popular choice, it offers several notable benefits—especially for developers already invested in the Apple ecosystem. Key Advantages Performance Considerations As a compiled language, Swift often runs faster than languages like Python or R. This can be especially beneficial when handling large datasets or complex computations. ...
